Cost Dynamic Management Research Based On Activity And Process Engineering

Since implement project bidding and the implementation of the bill of quantities, the construction enterprises have to "low price" strategy to bidding and The cost of construction enterprise existing laggard management methods. This result in construction enterprise profit space more and more small, for construction enterprise's survival and development to bring huge challenge. Cost management has become the lifeblood of a construction enterprise, and the dynamic management method is most research and practical value in currently cost management, so the method of dynamic management is of great significance to the contractor target profit margin. Based on this, the paper from the Angle of activities and process of the construction engineering cost dynamic management of further research.This paper summarize and generalization the international and domestic engineering cost of dynamic management, the present situation and the development, points out the current engineering cost dynamic management, and the problems existing in the valuation mode in the development of new requirements, in this paper, based on the process of engineering cost activities and dynamic management methods mainly include the cost of identifying and dynamic control two parts. In determining the engineering cost based on the activities and process the project cost determination method, using the construction project WBS recently decomposition technique sure project activities, then according to project activities to determine the construction project needed resources, according to the market price of resources to determine the engineering cost of construction projects. The dynamic control in engineering cost theory research based on activity and process the same Angle, in dynamic control of cost performance monitoring modified "earned value method", to more accurately solve construction period and cost integrated problem. Meanwhile the thesis analyzed the contractor under the perspective of the cost of each phase construction project affect the dynamic management, engineering cost of engineering change, claim events, material market price changes studied engineering change, the engineering claims management as a contractor a positive, initiative, and dynamic management means the cost is "open source" as the cost is an important means of dynamic management.The research in this paper to construction engineering project cost dynamic management research provides a new idea, which is beneficial to the contractor profit goal the realization, the more help contractor cost management concept of change, further strengthens the project contracting competitiveness.
